Remove acknowledgements and enable notifications

[emartine]

We keep getting "nagios failing to notify us" because individuals are supressing alerts by acknowledging them in some for or another. Is there a way to create a weekly purge of acknowlegements and enable notifications ?

Hello, @emartine. One way to get rid of all acknowledgments is to delete the retention.dat file.

/usr/local/nagios/var/retention.dat

So you could create a simple shell script that removes this file and put it in a cron.


PS: Deleting the retention.dat file will also delete all scheduled downtime and comments.

Deleting the retention.dat file will also delete all scheduled downtime and comments.

Meaning if it is active now that it will remove currently active scheduled downtime? Or it will remove any future scheduled downtime windows?

[npolovenko]

@emartine, It will remove all existing downtime records, whether downtime was scheduled for now and already started or if it's scheduled for some time in the future.

Is there a way to reimport those schedules in bulk?

@emartine, This sequence of commands worked for me do delete all acknowledgments without affecting scheduled downtime:

service nagios stop
sed -i "s/problem_has_been_acknowledged=1/problem_has_been_acknowledged=0/g" /usr/local/nagios/var/retention.dat
service nagios start

Please backup your XI before trying this.

This does remove the acknowledgements but doesn't seem to enable notifications.

@emartine, Can you run the same query with enable_notifications=1?

service nagios stop
sed -i "s/problem_has_been_acknowledged=1/problem_has_been_acknowledged=0/g" /usr/local/nagios/var/retention.dat
sed -i "s/enable_notifications=0/enable_notifications=1/g" /usr/local/nagios/var/retention.dat
service nagios start

I think you mean notifications_enabled=1 ?

I created a dashboard with a urldashlet

and although the page looks fine... when I have a report sent only the top part of the pdf is visible while the rest is blank.

Any idea why or what I can do to fix this?

The url dashlet I created was https://servername/includes/components/ ... viceattr=4
